PROCEDIMIENTO PARA ACELERAR LA FORMACION DE POLIADUCTO AL HACER REACCIONAR COMPUESTOS EPOXIDICOS CON MAS DE UN GRUPO EPOXIDO POR MOLECULA CON DICIANDIAMIDA EN CALIENTE.

摘要

The zinc complexes involved are those tertiary amines. The epoxy compds. which must have more than one epoxy grouping, and the dicyanodiamide, in the heated state react rapidly in presence of the accelerator at temps. of 140 degrees C or above to form the polyadduct.
